Thesis

Most academic publishers provide some way of asking permission to use an article through the website that hosts the content. A "request permissions" button will usually be available and will direct you to the service (such as the Copyright Clearance Center) that grants permission. These forms generally ask questions about what you plan to do with the content and usually have an option for reuse in a thesis/dissertation.

Generally, yes. You own the copyright to your thesis, which means you may reuse the work however you see fit as long as your reuse does not impact the University's ability to host a copy of the thesis on UWSpace (remember, you are required to provide a non-exclusive distribution licence to the University). If you did want to publish parts of your thesis as a journal article or as part of a scholarly book, you would also be responsible for clearing the copyright of any third-party materials (including images, figures, tables, and longer quotations) in the later manuscript.
